Subject [jira] [Commented] (CASSANDRA-10023) Emit a metric for number of local read and write calls
Date Fri, 20 Nov 2015 12:34:10 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-10023?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15016724#comment-15016724
] 

Sylvain Lebresne commented on CASSANDRA-10023:
----------------------------------------------

This is marked ready to commit, but I don't see any comment regarding who +1ed that patch
(and JIRA's history say it's "Anonymous"), and I think some response to [~cburroughs] comment
is probably in order (using a Meter does sound reasonable).

Also, which version is the patch targeting?

> Many C* drivers have feature to be replica aware and chose the co-ordinator which is
a replica. We should add a metric which tells us whether all calls to the co-ordinator are
replica aware.
> We have seen issues where client thinks they are replica aware when they forget to add
routing key at various places in the code.
